or hearing improvement. Fig. 2 is a sectional view showing the appliczv tion of my invention to an oiling-cup,-and modification. 4 is an enlarged plan view of the plug of fibrous material removed from its holder.- i

The essential feature of my invention lies, in the provision of a seal for the oiling-hole or oil-cup of abearing, journal-box, or hub,- this seal consisting of felt or other fibrous material adapted to close the oil-hole, but having an opening to receive and make a tight joint with the nozzle of the oil-can, as I will describe I In Fig. l, A indicates an axle orshaft which turns in or on which turns ajournal-box, t hearing, or hub B. In this part B is an oiling-opening b, which for the purpose of my in rention may conveniently be enlarged for the reception of a plugC. This plug is of} felt or other fibrous material. The en large I the axle or shalt; b opening Z) cup-shaped oil-space is left between the inner face of the plug and the axle or shaft. This plug Chas a small perforation or opening I) through it l adapted to receive and to make a tight joint l with the nozzle E of an oil-can. In other words,when the nozzle of an oil-ean is thrust D in the plug the latter forms a sort of stnliing-box between i the oil-can nozzle and oil-hole, so that when 5 the oil-can is, as usual, pressed to fort-e the oil out of the can th pelled to flow into or, in fact,.is forciblypumped intothe bearing, where it is required, since the oil cannot escape in any other direction.

The plug described,especially when made of felt, has the additional advantage of olferingmany hairs or fibers in' the opening to prevent the admission of grit and dirt to the journal or hearing. j ,-In Fig.2 I have shown any invention as appl'iedto a simple form of oil-cup F, threaded to'be screwed into a correspondingly-threaded oiling-opening in a, hearing or hub.

In'Fig. 3 the plug C'is shown as mounted in t 1 a-uretal ferrule Ft, in which form it can be conveniently nrarketed forapplication to existing oiling holes or cups." I claim as my invention v 1 The combination with a bearing having an oiling-hole therein, of a seal for said hole, consisting of a plug of'fibrous material adapted to close the oil-hole', said plug having an diameter as, first, to make a tight joint with the nozzle of an oil-can when the latter is inserted for oiling, and, second, to permit t he fibers to rawn,whereby Waste of oil is prevented, and dust or grit excludedfrom the bearing, substantially as described.

2. The combination with a bearing having an oil-hole therein, of a seal for said oil-hole, consisting of a plug of felt adapted to close the oil-hole and having an opening of such diameter, as, first, to make a tight joint withthe nozzle'of an oil-can when inserted therein, and, second, to permit the fibers to screen the opening when the nozzle is withdrawn,whereted, and dust or grit excluded from the bearing, substantially as The combination of a hearing or hub having an opening over and about the oilhole,with a fibrous plug fitted into said opentight joint with the nozzle of an oil-can when inserted therein, and, second, to permit the fibers to screen the opening when the'nozzle is withdrawn, whereby waste of oil is prevented, and dust or grit excluded from the bearing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
